Description
Size: Max length 10.0 cm CW (male); 8 cm CW (female)

The crab has a rather shaggy tomentum, three large anterolateral carapace teeth, about 16 small spines on the inner margins of the first two pairs of legs, and the joint between the fifth and sixth abdominal segments is partially fused. In mature female, the sternal sutures 7/8 end on large conical tubercles just behind the bases of the chelipeds. Dectyli as long as propodi in anterior ambulatory legs.
The carapace is clearly broader than long, except in very young specimens (Cl: 6.5 mm) in which the length equals the width. The fifth pereiopods are only moderately longer than the fourth. P5 extended forward reaches slightly beyond the last anterolateral tooth of the carapace. In smaller females (Cl. 10-13 mm) the sternal grooves and between the bases of P3 and are not elevated. In the next largest female (C1. 36mm) and in larger specimens these grooves extend to the level between P1 and P2. Small ovigerous specimens show the presence of tubercles at the end of sternal grooves which otherwise are only found in much larger adult specimens.
